Honestly I had no idea this coin existed, but after a little bit of googling, it seems that there is some development going on with this coin, like integration with merchants. Usually when I see low market cap coin with a steep rise, first thing that comes to my mind is Pump and dump. This is probably not the case here, as Graftcoin looks like a solid alt and a real deal.
It is a big market and there is actually no way you can have an idea of all the coins in the market.
I actually invested in graft a while back during their ICO which was done using the NEM smart contract platform before moving to their own mainnet immediately after the ICO and I can tell that a lot of development has been going on with the project lately based on it being a payment system and the team are really doing some pretty good work.
The potentials are there and even though it is not even in a big exchange yet, I believe it is a good one to hold for the long term. Now the whole market is down and that includes Graft that has gone low as well, so in the case of a bounce like that, it is possible it reaches the bottom and the smart investors are picking the dips up.
